Background Birthweight and gestational age are important factors of not only newborn health by also child development and can contribute to delayed cognitive abilities. However, no study has analyzed the association of birthweight and gestational age with school trajectory measured simultaneously by school entry, grade repetition, and school dropout. This study aims, first, to analyze the association of birthweight or gestational age with school entry, and second, to explore the relationship between birthweight or gestational age and grade repetition and school dropout among children in Ouagadougou, Burkina Faso. Methods This study used longitudinal data from the Ouagadougou Health and Demographic Surveillance System. Our samples consisted of children born between 2008 and 2014 who were at least three years old at the beginning of the 2017–18 school year. Samples included 13,676, 3152, and 3498 children for the analysis of the school entry, grade repetition, and dropout, respectively. A discrete-time survival model was used to examine the relationship between birthweight or gestational age and school entry, grade repetition, and dropout. The association between birthweight or gestational age and age at school entry were assessed using a Poisson regression. Results The incidence rate of school entry was 18.1 per 100 people-years. The incidence of first repetition and dropout were 12.6 and 5.9, respectively. The probability of school entry decreased by 31% (HR:0.69, 95%CI: 0.56–0.85) and 8% (HR:0.92, 95%CI: 0.85–0.99) for children weighing less than 2000 g and those weighing between 2000 and 2499 g, respectively, compared to those born with a normal weight (weight ≥ 2500 g). The age at school entry of children with a birthweight less than 2000 g and between 2000 and 2499 g was 7% (IRR: 1.07, 95%CI: 1.06–1.08) and 3% (IRR: 1.03, 95%CI: 1.00-1.06) higher than children born at a normal birthweight, respectively. Gestational age was not associated with school entry or age at school entry. Similarly, birthweight and gestational age were not associated with grade repetition or dropout. Conclusion This study shows that low birthweight is negatively associated with school entry and age at school entry in Ouagadougou. Efforts to avoid low birthweights should be part of maternal and prenatal health care because the associated difficulties may be difficult to overcome later in the child’s life. Further longitudinal studies are needed to better understand the relationship between development at birth and school trajectory.

We present substantial evidence for the existence of a bias in the distribution of births of leading US politicians in favour of those who were the eldest in their cohort at school. This result adds to the research on the long-term effects of relative age among peers at school. We discuss parametric and non-parametric tests to identify this effect, and we show that it is not driven by measurement error, redshirting or a sorting effect of highly educated parents. The magnitude of the effect that we estimate is larger than what other studies on 'relative age effects' have found for broader populations but is in general consistent with research that looks at professional sportsmen. We also find that relative age does not seem to correlate with the quality of elected politicians.

This study examined the associations between school entry skills and science achievement at both the student and school levels among fourth-grade students in South Korea, Singapore, Japan, Chinese Taipei, and Hong Kong. Data of the five Asian regions in the 2015 Trends in International Mathematics and Science Study (TIMSS) were analysed. Variables included Interest, Self-concept, School entry skills - reported by parents, Cognitive activities, Parent attitudes toward mathematics and science, Home educational resources, and Gender, all at the student level, and Emphasis on academic success, Discipline problems, and School entry skills – reported by principals at the school level. Results of the multilevel path analysis indicated that School entry skills positively and directly influenced science achievement, and simultaneously mediated the influence from cognitive activities to science achievement at the student level. These findings were consistent among the five Asian regions. At the school level, it was found that compared to School entry skills, School emphasis on academic success was the stronger predictor of science achievement among students for most Asian regions. Implications for improving primary school students’ science learning are discussed.

BackgroundThe number of out-of-school children and adolescents has been increasing globally. In sub-Saharan Africa, an estimated 23 million adolescents leave school due to poverty, teenage pregnancy, and unspecified illnesses. The reasons for absenteeism are well-known but the factors involved in the decision to return to school have not been analyzed. This study aimed to identify the factors that promote primary school re-entry among chronic adolescent absentees in rural sub-Saharan Africa.MethodsQualitative data were gathered through participant observation, in-depth interviews, and focus group discussions involving nine pupils who returned to school after chronic absenteeism and 140 adult stakeholders in Mbita sub-county, Kenya. Data were analyzed using thematic analysis.ResultsThe thematic analysis results showed that four factors promoted school re-entry, namely: (1) social norms: “school for a better life”; (2) linkage of community and school; (3) supportive environment; and (4) using discipline to make adolescents serious about their education.ConclusionsSchool re-entry among chronic absentees in Mbita sub-county is promoted by both community and school factors. It was observed that social norms regarded an education as a “passport to a better life.” Adolescents, teachers, and community leaders view education as a means of improving one’s socio-economic status. Two essential elements of health-promoting schools, a supportive environment and a linkage with community, effectively promoted returning to the school among adolescents. The introduction of health-promoting schools was recommended to implement a school re-entry policy in Kenya effectively.

•76% of parents had at least one school-related concern during the COVID-19 pandemic.•Over half of parents worried their child’s learning declined during the pandemic.•Some COVID-19 and school parental concerns made child vaccination more likely.•A hypothetical vaccine mandate may increase parent likelihood of child vaccination. We assessed the impact of a hypothetical school-entry COVID-19 vaccine mandate on parental likelihood to vaccinate their child. We collected demographics, COVID-19-related school concerns, and parental likelihood to vaccinate their child from parents of patients aged 3–16 years seen across nine pediatric Emergency Departments from 06/07/2021 to 08/13/2021. Wilcoxon signed-rank test compared pre- and post-mandate vaccination likelihood. Multivariate linear and logistic regression analyses explored associations between parental concerns with baseline and change in vaccination likelihood, respectively. Vaccination likelihood increased from 43% to 50% with a hypothetical vaccine mandate (Z = -6.69, p < 0.001), although most parents (63%) had no change, while 26% increased and 11% decreased their vaccination likelihood. Parent concerns about their child contracting COVID-19 was associated with greater baseline vaccination likelihood. No single school-related concern explained the increased vaccination likelihood with a mandate. Parental school-related concerns did not drive changes in likelihood to vaccinate with a mandate.

Young age at school entry (ASE) is related to attention-deficit/hyperactivity disorder in higher grades. The reason for this association is unclear, but medical oversupply and stress-related factors are discussed. We aimed to investigate whether ASE is associated with reported symptoms of attention-deficit/hyperactivity (ADH) already in first grade. Data of a population-based prospective cohort study ( N  = 2003; Mainz-Bingen region; Rhineland-Palatinate; Germany) with baseline assessments prior to school entry and two follow-ups during first grade were analysed. ADH symptoms were assessed by parent and teacher versions of the Strengths and Difficulties Questionnaire. Associations between ASE and scores of the hyperactivity/inattention subscale (range 0–10) were investigated by regression analysis and adjusted for potential confounders and baseline symptoms prior to school entry. In total, 1633 children (52% boys, mean ASE 6.5 years) were included. There were no relationships between ASE and parent-reported scores of the hyperactivity/inattention subscale prior to school entry and 3 months thereafter. However, at the end of first grade, ASE was negatively associated with the hyperactivity/inattention subscale in parent (− 0.7 subscale points per year ASE, standard error = 0.16, p  < 0.0001) and teacher reports (− 1.2 subscale points per year ASE, standard error = 0.25, p  < 0.0001). This ASE effect appeared more pronounced in girls than in boys. Young ASE is related to more reported symptoms of ADH at the end of first grade, but not before. The evolvement of this effect during first grade may be a clue to ASE-related stress factors.

Background The Human papillomavirus vaccine (HPV) is an essential tool for the prevention of HPV-related cancers. In Puerto Rico, the Secretary of Health established a school entry requirement of at least one dose of HPV vaccination in girls and boys aged 11 and 12 years, taking effect in August 2018. Our study aimed to examine parents’ and guardians’ views of unvaccinated children about the process of implementation of the new HPV vaccination school entry policy in Puerto Rico and identify potential barriers and facilitators related to the implementation of this requirement. Methods During April through November 2019, we conducted three focus groups ( n  = 12) and eight in-depth semi-structured interviews with parents of children aged 11 and 12 who had not yet initiated the HPV vaccine series. The interview topics addressed were: perception of vaccination, HPV vaccine and it is inclusion as new school entry requirement practice, procedure of the sources of information, influencers, and willingness to change. The interviews were recorded and transcribed by our staff members. We identified emergent themes through thematic analysis. Results The participants’ perspective on the HPV vaccine school requirement was mixed. Lack of information of the HPV vaccines and lack of communication about the school-entry requirement were the themes most mentioned in the interviews. Moreover, previous negative experiences from friends or family members and adverse effects deterred some participants from vaccinating their kids. We discussed barriers in the process of soliciting an exemption. Conclusion Most barriers mentioned by study participants are modifiable. Information about the HPV vaccine mandate’s implementation and educational materials regarding HPV vaccine safety need to be provided to address parents’ concerns related to the vaccine’s side effects. Schools (teachers, principal directors, and administrative staff), the government, and parent organizations need to be part of these efforts. This multilevel approach will help to improve disseminating information about HPV vaccination to clarify doubts and misinformation among parents.

•School entry vaccination program involved checking, providing catch-up vaccination.•It contributed to increase in vaccination coverage and lower incidence of measles.•Guizhou experience may be useful for other countries looking to adopt this strategy. Guizhou Province of China implements a vaccination program specifying that children’s vaccination records are to be checked upon entry to kindergarten and primary school; children missing one or more recommended vaccinations are to be offered the missed vaccinations; school-level vaccination coverage levels are assessed at the time of school enrollment and six months later to monitor compliance rates. We obtained the number of doses of each vaccine in the national immunization schedule that were administered before and six months after kindergarten and school enrollment and reported to Guizhou Province during 2004 through 2018. We determined temporal trends in coverage of the second dose of measles-containing vaccine (MCV2) and other vaccines, incidence of measles, and number of school-based measles outbreaks. MCV2 coverage at kindergarten entry increased from 53% in 2004 to 98% in 2018. Among children missing one or more vaccinations, the six-month catch-up rate of MCV2 increased from 80% in 2004 to 99% in 2018. Among primary school children, coverage of MCV2 and other recommended vaccines had similar increases. The annual incidence of measles among Guizhou’s total population declined from 280 per million in 2003 to 0.3 per million in 2018. There have been no measles outbreaks in kindergartens or schools since 2015. Checking vaccination record at kindergartens and primary schools and providing necessary catch-up vaccination was associated with increased coverage of measles and other vaccines, lower incidence of measles, and an apparent end to school-based measles outbreaks. Guizhou’s experience of checking vaccination records at school enrollment led to implementation of this strategy in other provinces. In 2019, the kindergarten and school entry vaccination record check program was incorporated into China’s national vaccine law.

ObjectivesLittle is known about immunization coverage among kindergarten-aged children in jurisdictions that do not require children’s immunization records to be provided at school entry. Thus, we assessed immunization coverage and associated characteristics of a 2008 birth cohort of Alberta children at kindergarten entry as compared with at the end of grade one.MethodsThis retrospective cohort study used population-based administrative health data for childhood vaccines in Alberta, Canada. We categorized and compared immunization status of children as follows: (a) complete at kindergarten entry; (b) incomplete at kindergarten entry but complete at the end of grade one; and (c) still incomplete at the end of grade one. To assess factors associated with immunization status, we used multinomial logistic regression.ResultsImmunization coverage for the complete vaccine series for children (N = 41,515) at kindergarten entry was suboptimal (44.5%, 95% CI 44.0–45.0) and substantially lower than for children at the end of grade one (74.8%, 95% CI 74.3–75.2). Young maternal age, not living with a partner, and having > 1 child in a household were associated with incomplete immunization status at kindergarten entry. Midwife-assisted hospital and home delivery was strongly associated with incomplete immunization status at the end of grade one.ConclusionImmunization coverage at kindergarten entry was strikingly low. Risk factors for incomplete immunization status were identified that require particular attention when addressing immunization coverage. The school-based catch-up immunization program in grade one seems to have substantially improved coverage among children, suggesting a potential benefit of shifting the catch-up program from grade one to kindergarten entry.

Children’s motor development is socially unevenly distributed despite many municipal exercise programs (EXP). It has not been sufficiently investigated whether and how they appeal to children from different social backgrounds. This study investigates the use of municipal EXP in preschool age and the association between participation and motor development considering social circumstances. In school entry health examinations, parents were asked about participating in various EXP (response = 65.5%; n = 6480). Motor development, i.e., body coordination and visual-motor coordination, were assessed by a social pediatric development screening, and social circumstances by migration background (MB) and parental education (PE). Poisson regression estimated adjusted Incidence Rate Ratios (IRR; 95% confidence interval, 95%—CI) for relationships between social circumstances and participation in programs and participation and body coordination/visual-motor coordination. Children with MB (IRR 0.73; 95%—CI 0.71–0.75) and low PE (IRR 0.45; 95%—CI 0.40–0.50) used EXP less often. Children participating less often have a finding in body- (IRR 0.76; 95%-CI 0.63–0.90) and visual-motor coordination (IRR 0.47; 95%—CI 0.35–0.62). Significant effects were found for children with and without MB and higher PE. Municipalities should make EXP more attractive for families with MB and low PE.
